Sumatinath was born at Ayodhya in the
Ikshvaku clan. His father's name was King Megharath and Mother Queen
Sumangla or Mangala Rani His birth date was the eighth day of the
Baisak shukla. It is said that the soul of Purushasimha who
due to vigorous penance and higher spiritual practices, earned the Tirthankar-nam-and-gotra-karma
descended into the womb of queen Mangalavati or Sumangala, wife of king Megh of
Ayodhya.King Megharath named the new born as-Sumati (wisdom or right thinking).
Sumatinath in due course inherited the kingdom. King Megharath became an ascetic. After a long and peaceful
reign Sumatinath, too, became an ascetic. He attained omniscience under a
Priyangu tree on the eleventh day of the bright half of the month of Chaitra. He
established the four pronged religious ford and became a Tirthankar. On the
month of Chaitra Sukla 11 he got Nirvana at Samedshikharji.
